Sony's Infolithium is a Li-Ion battery, which is a different technology from NiMH. The following is copied from Cnet:


Yes, Li-Ion batteries have a (slightly) shorter lifespan, but the benefits far outweigh the loss. My (frequently used) Sony DV cam is over two years old and there is no degradation in battery performance (as far as I can tell). The battery is less than 1/4 the size of a similar Ni-Cad and they are much more environmentally friendly, if that is important to you.

The average Li-Ion is good for about 350-500 (100% capacity) charges (cycles). Cycle numbers of over a thousand can be expected before the capacity gets too low to be usable. More info at AGM Batteries Ltd : Li-Ion Technology

Ni-Cad - big, bulky, short life, and have a memory effect that dramatically reduces battery life if you don't completely discharge them before re-charging. Avoid Ni-Cad if other options are available.

Nickel-metal hydride (NiMH) replaced and improved upon Ni-Cad in every respect. NiMH batteries are lighter and have only a moderate memory effect. You should "deep-cycle" (ie. completely drain) an NiMH battery as often as is convenient to maximise battery life, but it is not imperative that you do so each and every time you charge. If convenient, it's good to deep-cycle NiMH batteries at least once a week or two.

Lithium-ion (Li-Ion) batteries are even lighter than NiMH and have no memory effect. Li-Ion batteries are the most convenient of the standard battery types to use because you can recharge them whenever it's convenient. The have an integrated microchip to prevent overcharging and provide other information to the user -- time remaining.
